Metalachi to mix mariachi with metal at Boise concert

When Ozzy Osbourne sang about “goin’ off the rails on a crazy train,” he had no idea how looney that his tunes actually would get years later. “The world’s first and only heavy metal mariachi band,” as Metalachi calls itself, is strangely entertaining while performing “Crazy Train.” And songs by AC/DC. Or Motorhead. Don’t misunderstand: Metalachi is ridiculous. But these comedians are better musicians than you’d expect. (The violinist shreds on Metallica’s “Master of Puppets.”) You’ve got to experience it live to grasp the genius of it, cabeza banger.
